Web8 de mai. de 2024 · During inflation, scalar fields, including the Higgs boson, may acquire a nonzero vacuum expectation value, which must later relax to the equilibrium value during reheating. WebHá 1 dia · However, the Higgs field behaves differently by having a positive mass in empty space, which means that even in the absence of any particles, the Higgs field has a certain value at every point in space. This value, known as vacuum energy or vacuum expectation value, for the Higgs field, is 246 GeV.
